ios - UNNotificationAction未显示在远程通知中

我实现了可操作的远程通知，但是notification出现时，操作按钮未显示。

有效负载

{“aps”:{“alert”:“正在测试。
(11)“，”徽章“:1，”声音“:”默认“}，”类别“:” newnote“}

我的代码

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        self.configureUserNotifications()
        self.registerForRemoteNotification()

        return true
    }


func registerForRemoteNotification() {
    let center  = UNUserNotificationCenter.current()
    center.delegate = self
    center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
    if error == nil{
        UIApplication.shared.registerForRemoteNotifications()
    }
}


func configureUserNotifications() {
        let acceptAction = UNNotificationAction(identifier:
            "accept", title: "✅ Accept note", options: [])
        let rejectAction = UNNotificationAction(identifier:
            "reject", title: "❌ Reject note", options: [])
        let category =
            UNNotificationCategory(identifier: "newnote",
                                   actions: [acceptAction,rejectAction],
                                   intentIdentifiers: [],
                                   options: [])

        UNUserNotificationCenter.current()
            .setNotificationCategories([category])
    }



    func application(_ application: UIApplication,
                     didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Registration for remote notifications failed")
        print(error.localizedDescription)
    }

    func application(_ application: UIApplication,
                     didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("Registered with device token: \(deviceToken.hexString)")
        self.deviceToken = deviceToken.hexString
    }


    //Called when a notification is delivered to a foreground app.

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("User Info = ",notification.request.content.userInfo)
        completionHandler([.alert, .badge, .sound])
    }

    //Called to let your app know which action was selected by the user for a given notification.

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print("User Info = ",response.notification.request.content.userInfo)
        print("Response received for \(response.actionIdentifier)")

        if response.actionIdentifier == "accept" {

        }
        else if response.actionIdentifier == "reject" {

        }
        completionHandler()
    }

最佳答案

我认为，如果将UNUserNotificationCenter.current() .setNotificationCategories([category])移至registerForRemoteNotification函数，该问题将解决。像这样:

 if #available(iOS 8.0, *) {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: Set([category]))
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    }
